Abstract

A wireless device may send uplink transmissions to a base station. The wireless device may use multiple spatial domain transmission filters for sending repetitions of data and/or control information in the uplink transmissions. The spatial domain transmission filters may be determined based on an indication from the base station and/or one or more spatial domain transmission filter(s) used for receiving control information from the base station.

11 . A method comprising:

transmitting, by a base station to a wireless device and based on a transmission configuration indication (TCI) state, downlink control information (DCI) comprising an indication of a sounding reference signal (SRS) resource;

receiving, based on the SRS resource, at least one repetition of a transport block via one or more first repetition occasions; and

receiving, based on the TCI state, at least one repetition of the transport block via one or more second repetition occasions.

12 . The method of claim 11 , further comprising:

transmitting a medium access control control element (MAC CE) activating the TCI state.

13 . The method of claim 11 , further comprising:

transmitting one or more indications of a quantity of a plurality of repetition occasions of the transport block, wherein the plurality of repetition occasions comprises the one or more first repetition occasions and the one or more second repetition occasions.

14 . The method of claim 11 , wherein each of the one or more first repetition occasions and the one or more second repetition occasions comprises a same radio resource allocation for the transport block.

15 . The method of claim 11 , wherein the one or more first repetition occasions and the one or more second repetition occasions are time division multiplexed.

16 . The method of claim 11 , wherein:

the receiving the at least one repetition of the transport block via the one or more first repetition occasions comprises receiving the at least one repetition of the transport block via a first uplink beam; and

the receiving the at least one repetition of the transport block via the one or more second repetition occasions comprises receiving the at least one repetition of the transport block via a second uplink beam.

17 . A wireless device comprising:
